HEELPoL|sH|NG MAcHiNE.

Specification forming part of Letters Patent. No. 39,546, dated August 18, 1863.

To all whomit muy concern:

Be it known that I, BENJ. Q. BUDDTNG, ot' Milford, county of Worcester, and State of Massachusetts, have invented a new and Improved Heel- Polishing Machine; and I do hereby declare that thefollowing, taken in connection with the drawings, which accompany and form part of this specification, is adescription of my invention sufficient to enable those skilled in the art to practice it.

My invention relates to certain improvementsin polishing-machines5 and it consists in the construction and operation ot' mechanism for surfacing or polishing heels of boots and shoes.

My machine is shown in Sheets l and 2 of the accompanying drawings. Figure 1 represents a. top view; Fig. 2, a frontelevation, and Fig. 3, aside eleva-tion of Vthe same. Fig. 4 is a section, taken on the line .rx of Fig. 2. Figs. 5 and 6 are views of one vof the polishingtools. Figs. 7 and S are views of the plate and springs against which the heel is held while being polished. A y

In the drawings, A denotes theframework of the machine; B, a vertical rod joined at its lower end to a treadle or foot-lever,C, and

bearing on its upper enda last or shoe-holder, f

which supports the shoe D, the heel of which is to be polished. to the top of the rod by a universal joint, so that the shoe will be capable of a lateral or The rod B slides vertically through a plate, a., and in such manner that when at its lowest position the rod may be tipped forward, (by means of a slot, b, in the plate and corresponding portion c ot' the rod,) for the purpose of fixing the shoe upon. the last, or removing it therefrom. The shoe is kept at its highest position, or in place to he operated upon, by a counter-balance weight, E, which being applied to the rear end of the treadle O kcepsthe opposite end and r the rod B elevated while the shoe is brought down from the polishing-tools by applying the V'Vheu at its highest position, the heel is clamped or borne against the plate d, or two springs', c c, applied thereto. When so clamped, the heel is presented to the action of a series of polishe'rs or polishing-tools, F F', arranged and operated as follows: As shown, the polishers are `placed one to operate against the back of The last maybe applied the heel, and one on each side thereof, though they may be arranged to operate over more or less of the surface as circumstances may require. Each tool, F, is hinged or jointed to the foot of a vertical arm, G, hung upon a ring, D, fixed upon atubiilar shaft, H, and so as lobe capable of movement at its lower end through slots d in a plate, e, toward and away from the shoe. Each polisher is so hinged to its arm that it can move thereon vertically to brin g its surfaceproperly against the sides o f different heels, according as said sidesore'dges may have more or less inclination to thel bottom surface of the heel. 'Io

.each arm G a curved spr-ing,f, :is applied,

clined and the springsf and arms Gr will be drawn in .in such a manner as toforee the polishers against the heel. tothe springs, instead of directly to the arms,

I obtain a variable pressure of the polishersv against the heels, instead of a positive unyielding pressure, and this enables the polishers to yield to any irregularities of surface in the heel, at whatever pressure the springs may have on the arms. A treadle, K, is conneeted at its front end by a link or rod, IL', to a rod, L, which, extending up over the' top of the machine, turns over, and is jointed to a shaft or pistou, J, which slides up and down in the shaft H. A bolt, g2, connects the collar I and shaft or pistonJ. A weight, 7a, on the rear end of the treadle, serves to keep the pistou J and collar I iu their normal position and the polishers out of contact with the heel, while pressure ot the foot on the front of the lever forces the polishers against the heel. Whenever they are so brought against the heel a reciprocating, rotary, or circular niotion is given to them, as follows: The rear of the plate e, in which the arms Gr work, has one end of an inclined crank-pin, g, jointed to it. The other end of the pin extends `and slides through a ball, h', of a universal joint, i, near the periphery of a crank-wheel, K'. Said wheel is fixed on a shaft, I, bearing afast pulley, m, 1

By jointing the links and aloose pulley, n, and rotating in bearings o o. Rotation ofthe shaft and crank-wheel imparts a rotary motion to the adjacent end of the cranlerod, while its other end is thereby actuated in such a manner as to impartl horizontal and reciprocating motions to the plate e, and thereby to the polishers.

To vary the length of throw of the polishers according to the size ofthe heel, or length of surface to be polished, is done as follows: The fast pulley is fastened to the shaft by a screw, lv. If we wish to shorten the throw of the polishers we loosen the fast pulley and slide the shaftl back. This lessens the inclination of the crank rod with respect to the axial line of the shaft I, and, as the inclination of the crank approximates to the line of the shaft,

the throw of the polishers will be proportionatt 1y lessened.' A rod, p, extendsup from the treadle K, and is fastened at the top to a shipping-lever, q, turning in bea-rings lr. 'When the polishers are out of contact with the heel, they are kept from horizontal movement by the belt being upon the loose pulley n. When the treadle'is depressed to force them into contact with the heel, the same movement ofthe treadle draws down the rod p and causes the lever q to shift the belt onto the fast pulley m, thereby causing simultaneous'pressure of .th p )lishers against the surface cf theheel,` an-lv hoiizoutal movement over' the same. Withdrawalofthetoot orraising of thetreadle releases the polishers from contact with the heel, and at the same time stops their horizontal movement by slipping the beltback onto the loose pulley. The plate d, which forms the instrument against which the bot- .tom surface of the heel, (or while being op- @rated upon the top surface thereof,) -is applied to the shaft H by a shank-pin, s, which rotates freely in the shaft, and the plate is kept from rotation, when the machine is in operation, by a pin, t, thereon, which extends into a fork or wire, u, and is thereby kept from turning. The springs c,on the bottom of the plate, are so applied as to adapt the same to different sizes of heels. The tendency of the polishers, when working against the corners of the heels, is to pushup or form a ridge of the leather, and the springs are so applied as to bear down on theat surface of the heel and form an edge to the same, against which the polishers will work. They are made of such size and so applied that they extend out beyond the edge until the shoe is clamped' up to the springs, and, the polishersbeing forced up against them, vthey are made to conform to the edge thereof, and will then present a surface'to be worked against..

By my machine heels can be much more quickly and tinelynished than in the old method, where the polishing tool, is rubbed over the surface by hand.

I claim- 1. The polishers F, when arranged so as to be capable of simultaneous pressure against and reciprocating,r rotary movement around the edge or'side of the heel, as set forth.

2. The combi-nation ofarms G, springs j', collar 1, and links g, or their equivalents, for producing the motion of the polishers against and. away from the heel, as above described.

3. The arrangement of mechanism, consisting of the plate` e, adjustable crank-pin g3,

joint t', and crank-wheel k, or the mechanical equivalent thereof, operati-ng together, substantially as described.

4. .Combining a pressure mechanism, as shown by the arm G, collar I, link g, shaft J,

rods I L, and treadle K, or other suitable mechanism, for producing the pressure f the polishers with a shipping mechanism (consisting of lever q and rod p, or their equivalent) for their simultaneous operation, substantially as above set forth. l -5. In combination with the bearing platev d the' springs c c, operating in manner and for the purpose as'descrbed above.
